Intercompany Purchase Scenario of Service Materials (DIEN)

Hi,

I'm trying to find documentation about how to configure this scenario in SAP.

But I obtain this error:

Material not subj. to inventory mgmt. in plant 3000 (Pl. check your input)

Message no. ME124

when I'm creating the Purchae Order.

If I do the same with a normal vendor I can buy a DIEN, but if this is an intercompany scenario I can't. I understand that It's not necessary storage location view of a material because we don't have to entor or move stock.

Can anyone help me?

Thanks in advance.
